Sub-Bituminous Rochelle Mine

5 FT Liquids Production

6 LGTI Summary Operated at Dow Chemical s Louisiana Division under Synfuels Corporation Contract Over one third of the coal-to-power gasification in U.S. Supplied Syngas to two Siemens Westinghouse W501D5 turbines 2400 TPD sub-bituminous coal feed (1.5 X scale-up) Over 3.7 million tons of sub-bituminous coal processed Included significant testing of dry particulate removal system and petroleum coke and bituminous coal (second stage only)

7 Wabash River One of the Cleanest Coal Fired Power Plants in the World 1.7 million tons of bituminous 1.3 million tons of petcoke 2500 TPD bituminous coal feed 262 MW Net output Operational since 1995 at Cinergy s Wabash River Plant SG Solutions LLC now owns Syngas Plant, ConocoPhillips provides professional services on site Source: SG Solutions, LLC
